Trekking condition mid of May

Hi,

I am lucky and have found some time to trek the GR 20. Unfortunately the time I have to spend is a bit early in the season. My plan is to start from Calenzana the 20th of May and finish in Conca around 15 days later. I feel a bit unsecure about some matters. I hope there is someone at this excellent forum that could help me with some answers.

How are the snow conditions this year? Will it be possible to do the trek without crampons etc.? (I am aware of weather is very unpredictable and quickly changing especially in mountains).

Are the refuges staffed and will it be possible to buy supplies?

If the refuges are not staffed will it be possible to use the kitchen inside? Will there be gas?

Could I expect to find the refuges crowded at this time of year?

Best regard
Jens

Thanks for the good info. I think the snow condition (at present) looks Ok. I will start the hike the 20th of May.

I have sent e-mail to the Parc-naturel office and some tourist information offices in Corsica asking if the refuges is staffed and supplies available at this time of year but non has answered.

It would be nice to know if I will be able to buy supplies during the hike or if I have to carry everything with me. If anyone knows the dates the refuges will be staffed and supplies available I would appreciate to receive that information very much.

Best Regards

Jens
